Backgrounds And Aims: Laparoscopic surgery techniques have been increasingly preferred to classic laparotomy by surgeons since 1987. However, this method has some important adverse effects on intra-abdominal organs. The aim of this study is to evaluate the effects of different pressures of CO(2) on apoptosis and p53 expression in cells in liver and spleen.
Methods: In total, 30 male Sprague-Dawley rats were used in the study. CO(2) was insufflated into the intra-abdominal cavity via angiocatheter cannule by an insufflator in two different pressures of 10 and 20 mm Hg for 60 min. However, in the control group, only cannule was inserted into the intra-abdominal cavity, but no gas was insufflated. After 60 min, the rats were killed and laparotomy was applied. The liver and spleen were excised. The samples were histologically processed and immunohistochemistry was applied.
Results: All the data revealed that the number of apoptotic cells in liver and spleen increases in proportion to CO(2) pressure level. No p53 expression was detected in both organs.
Conclusion: CO(2) pressure level and application time may affect on cells living in liver and spleen. High pressure and/or long application time may cause releasing of cytokines and superoxide radicals from these organs' cells, and transient or serious organ dysfunctions may occur.

Intravesical Bacillus Calmette-Guérin (BCG) immunotherapy for bladder cancer rarely leads to disseminated BCG infections, most of which occur early after BCG instillations or in immunocompromised patients. We report late-onset disseminated BCG infection after intravesical BCG immunotherapy in a non-immunocompromised patient. A 78-year-old non-immunocompromised man was admitted with fever and hepatosplenomegaly.

BACKGROUND Arterioportal fistulas (APFs) are abnormal connections between the arterial and portal venous systems, leading to portal hypertension (PH) and symptoms such as gastrointestinal bleeding, splenomegaly, and hepatic pain. Symptoms typically appear by the age of 2 years in about 75% of cases. CASE REPORT A 7-year-old boy with an asymptomatic APF developed life-threatening complications following a Clostridium difficile infection.

Background: The inclusion of sustainable protein sources in poultry feed has become essential for improving animal welfare in livestock production. Black soldier fly larvae are a promising solution due to their high protein content and sustainable production. However, most research has focused on fast-growing poultry breeds, while the effects on native breeds, such as the Bianca di Saluzzo, are less explored.

The occurrence of hepatitis E virus (HEV) in patients with Schistosomiasis mansoni (SM) is still poorly understood in Brazil. The objective of this study was to estimate the seroprevalence of anti-HEV IgG in patients with SM and its association with the periportal fibrosis (PPF), assessed by serum markers and ultrasound criteria. This cross-sectional study was carried out in an endemic area in Pernambuco, Brazil, with schistosomal patients who underwent coproscopic survey.

To explore its effect on intestinal health and evaluate its safe dosage, 30 weaned pigs were randomly allotted to five groups and fed with a basal diet supplemented with different doses of CM for 42 days.
